“…However, regardless of perspectives, the phenomenon of potential breed specifi city imposes limitations -it is not always possible to determine the association between different alleles of IGF-I and productive traits. The results, obtained using egg-laying hens of Turkish selection, coincide with the data, presented in this article, -no associations between various allelic variants by HinfI-polymorphism in the promoter fragment of IGF-I and egg quality traits were determined (Daş et al, 2018).…”

Aim. To study the egg quality traits of Poltava Clay chicken line 14 and Rhode-Island Red chicken line 38 with different genotypes of the prolactin gene (PRL), growth hormone gene (GH), growth hormone receptor gene (GHR), insulin-like growth factor I gene (IGF-I) and Mx gene (Mx). Methods. The study was conducted using the method of polymerase chain reaction and restriction fragment length polymorphism analysis (PCR-RFLP). Results. We found signifi cant differences in line 14 for egg quality between prolactin, growth hormone, growth hormone receptor and Mx loci. Homozygous individuals CC and TT by prolactin locus prevailed over heterozygotes CT for egg weight on the 30th week of life. As for the growth hormone gene, the maximum differences for egg weight were revealed when comparing BC heterozygotes with CC homozygotes. As for the growth hormone receptor gene, signifi cant prevalence (p < 0.05) of individuals with the B0 genotype over A0 by parameters of egg yolk weight was noted at the age of 52 weeks. Signifi cant differences (p < 0.05) in eggshell thickness were determined for genotypes AG and GG by Mx gene in week 52. There were signifi cant differences (p < 0.05) in egg quality traits for prolactin and Mx gene for chickens of line 38. TT homozygotes by prolactin locus are characterized by the prevalence of values (p < 0.05) for the egg, yolk and shell weight. In case of Mx gene polymorphism, the heterozygous individuals were characterized by signifi cantly higher values (p < 0.05) of egg and albumen weight on the 30th week of life. There were no signifi cant differences in both experimental chicken lines for other egg quality traits between individuals with different genotypes. Conclusions. The data obtained are recommended for the use in breeding programs for Poltava Clay chicken line 14 and Rhode-Island Red chicken line 38 with the aim of obtaining microlines with the different genotypes for PRL, GH, GHR and Mx loci.

“…Three laying hen breeds of White Leghorn (WL), Lohmann Brown (LB) and Ataks (AT) were kept for egg production in Turkey. Ataks hen is a crossbred laying hen from Rhode Island Red × Plymouth Rock chickens [7]. The highest of egg production rate in White Leghorn hens at Turkey was reached of 100.0% (free-range) and 91.60% (indoor) [8].…”

Breeds characterization can be performed based on their phenotypic traits. In poultry, the breeds characterization can be performed based on the egg characteristics. This study was carried out to characterize three Turkish laying chicken breeds (30-49 weeks of age) of White Leghorn (WL), Lohmann Brown (LB) and Ataks (AT) based on their characteristics. Total of 90 new stock eggs (30 eggs/breed) from Görukle market, Bursa city, Republic of Turkey were used for analysis. Three statistical analyses of principal component analysis (PCA), canonical discriminant analysis (CDA) and hierarchical cluster analysis (HCA) analysis were used for breeds characterization. According to egg size index, most of eggs in this study had normal size type. The highest coefficient of correlation (0.99) value was showed between egg weight (EW) and specific gravity (SG). The PCA revealed that four principal components (4PC’s) of egg characteristics capable to explain the total variance of egg characteristics in WL and LB hens about 83.10% and 78.95% respectively. Meanwhile, 3PC’s of egg characteristic in AT were explained about 81.70% of total variance in egg characteristics. The Euclidean distance revealed that LB and AT hens were grouped into similar cluster and WL hen was grouped into different cluster. In conclusion, the egg characteristics in birds study can be used to characterize of WL (73.3%), LB (93.0%) and AT (76.7%) hens.
